1 Claim.

-. horizontal extensions of the tracks.

Such tracks are sometimes irregular in form or position so that therollersof the door bind in or on the tracks, making the operation of thedoor diflicult or troublesome hence the object of the present inventionis to provide an improved construction whereby the rollers on the dooraccommodate themselves to irregularities in the tracks. I

The invention is embodied in the example herein shown and described thefeatures of novelty being finally claimed.

In the accompanying drawing:

Fig. l is a front view of a fraction of the lower portion of a dooraccording to the invention and of the species herein first referred to.

Fig. 2 illustrates in front view a detail of one of the hingesconnecting the door sections equipped with the spindle and roller thelatter being in section.

Fig. 3 is a top plan view of the detail shown in Fig. 2 with the guideor track arrangement added the latter being in horizontal section.

In the views 5 designates the door panels these 35 being connected attheir ends by hinges including leaves 6 and 7 fastened to adjacentpanels and having perforated alined ears 8 and 9 respectively connectedby a pintle 10 held from accidental removal by a cotter pin 11. On thelaterally projecting end of the pintle is loosely placed the roller thatin the instance shown includes generally a hub 12 and a rim 13 withroller bearings between the rim and hub.

In the example shown the rollers are of a form to travel in. guides orchannels 14, 14, at opposite sides of the door frame, said channelsbeing of sheet metal bent at its front and. rear sides so as to confinethe roller. Said channels or guides are shown as bolted to an angle iron15 that in turn is bolted to the door frame 16.

Such doors are usually, in practice, counterbalanced or partlycounterbalanced by a spring or springs acting on cables 17 the latterattached to lateral pins 18 suitably secured to brackets at the oppositecorners of the lowermost panel of the door. The door can therefore bequite easily operated because as it is raised its weight is transferredto the horizontal tracks or channels. Such a door is particularly usefulin the construction of garages but can be used in other structures andby the term door I include a shutter or any analogous structure forclosing an opening.

It will be noted that each roller, by reason of its capacity for lateralmovement or play on its spindle, readily shifts inward or outward on thespindle to accommodate itself to any irregularities in the channel or ona track so that easy traveling is insured.

The forms of the parts can be changed without departing from the gist ofthe invention as
